june 2012 Randys Electrical Corner - relay Setup - Photo 36028514

Here is the relay setup that I didn’t show you in the last picture. Someone once told me it was a kind of logic switch, but I just see three relays. By feeding power to the two door relays as long as one is closing the circuit, I can automagically make the whole thing shut off by opening the other one. If you wanted to, though, you could replace relay 1 with a switch. That would allow you have the lights stay on with both doors open, and then you can shut them off with the simple flick of a switch when the doors are removed. I threw out the buzzer wire because I just hate it. Not the wire. I like wires. I hate buzzers. So I didn’t hook it back up again.
